BY BUCKHORN, CHEATHAM 8 BLORE United States Patent 3,099,036 SWIVELMOUNT FOR WINDOWS Flemming Bank, Portland, Oreg. (40 Moss Ave., Oakland,Calif.) Filed Apr. 12, 1961, Ser. No. 102,529 2 Claims. (Cl. 16-163)This invention relates to swivel or pivot mountings for windows, of thetype that enable a window to be swung from a closed position about a 180angle, to put the outside of the window in and the inside of the windowout.

A general object of this invention is to provide an improved swivelmounting of this description, which is relatively compact, and featuresno unsightly protrusions projecting from the mounting when the mountingsupports a window with the window closed.

More specifically it is an object of the invention to provide a swivelor pivot mounting for windows, which coma prises an unfolding hinge,including one member which swings 90 When the window is swung half wayabout, and another member pivoted to this one that swings 90 on swingingof the window to a position 180 from its original, closed position. Thehinge, with the window turned about, projects into a room thus to hold awindow casement inwardly of the window frame, and with window closed thehinge folds up with nothing protruding from the window frame.

Another object of the invention is to provide a swivel mounting forwindows, comprising an unfolding hinge of the type described thatincludes disconnectable guide means controlling pivotal movement of aplurality of pivoted members in the hinge whereby, during opening andswinging about of a window, various members in the hinge pivot in apredetermined sequence.

Yet another object of the invention is to provide a swivel mountingwhere spring-powered retarders are provided for braking free pivotalmovement of hinge members in the swivel mounting, in all positions ofthe mountmg.

A further object of the invention is to provide a mounting of the typedescribed above which is easy to inst-all and relatively simple inconstruction.

Yet another object is to provide a swivel mounting in the form of anunfolding hinge, which is relatively trouble free in operation, andwhere parts in the mounting in all positions of the mounting move inpositively defined paths by reason of pivots and guide structureprovided in the mounting.

These and other objects and advantages are attained by the invention,and the same is described below in conjunction with the accompanyingdrawings, wherein:

FIG. 1 illustrates portions of a window casement and window frame and anembodiment of the swivel mounting supporting the casement in the windowframe, with the window in its closed position;

FIG. 2 is similar to FIG. 1 but shows the casement swung to a position90 from the position in FIG. 1, and the swivel mechanism partiallyunfolded;

FIG. 3 is similar to FIGS. 1 and 2 but shows the casement swung to aposition 180 from the position in FIG. 1, and the swivel mounting fullyunfolded;

FIG. 4 is an enlarged illustration of the swivel mounting, showing itfully unfolded;

FIG. 5 is a section view, taken generally along the line 5-5 of FIG. 4;and

FIG. 6 is a section view, taken generally along the line 6-6 of FIG. 4.

Referring now to the drawings, in FIGS. 1, 2 and 3, 10 indicatesportions of a standard window frame, and 12 portions of a hinged windowsash, or casement, mounted in the usual manner within the confines offrame 10. In FIG. 1 the window casement is in its ordinary, closed3,099,036 Patented July 30, 1963 position. The part of the easement tothe left of the figure is the outside or exterior part of the casement,and at the right of the figure is the inside of the casement.

Mounting casement 12 within frame 10 is a swivel or pivot mounting 14,which accommodates swinging of the casement from the closed position inFIG. 1, to the open position in FIG. 2, and thence another 90 to thereversed position for the window illustrated in FIG. 3, where thenormally outside of casement 12 is on the inside and the normally insideof the casement is on the outside.

Considering now more particularly the construction of pivot or swivelmounting 14 in the embodiment of the invention shown, the mountingcomprises (with the window closed) an outer fitting or member 20, in theform of an upright plate, which is secured to the inside of window frame10, and an inner fitting or member 24, also in the form of an uprightplate, which is secured to the outside of casement 12. The outer andinner fittings are at the same elevation and have the same overall sizeand outline. Screws 26 are used in securing the fittings to the frameand casement. Between the inner and outer fittings is an elongated,upright, interconnecting link member or link 28.

Link member 28 has an end 28a which overlaps the lower end 20a of theouter fitting in all positions of the member. End 28a is the lower endof the link, with the mounting in its folded positions as shown inFIG. 1. Interconnecting end 28a of the link and end 20a of the fitting,for relative pivotal movement of the member and link about an axishaving a fixed position with respect to the member and link, is a pivotmeans 30. In the form of the invention shown this comprises a bearing 32joined to fitting 20 and journaled in link 28.

When opening the window casement it is preferable that it remainstationary in various adjusted positions, and thus a spring-poweredret-arder is included inhibiting free pivotal movement between the linkand outer fitting. The retarder is indicated at 34, and takes the formof a spring washer which bears, on one side, on link 28, and on theopposite side on a flange 38 of bearing 32. The washer functions topress the link against fitting 20, and the friction that results brakesthe two members from swinging completely freely.

Link 28 has an end 28b that overlaps in all positions of the member anend 24:: of the inner fitting. These two overlapping end portions areinterconnected by a pivot means 40 spaced laterally onlink 28 from pivotmeans 30. The pivot axis of means 40 has a fixed position with respectto the link and fitting 24. Pivot means 40 is similar to pivot means 30already discussed. Thus, 41 indicates a hearing which is joined to theinner fitting and journaled in link 28. A spring washer 44(spring-powered retarder) is interposed between the inner fitting andlink, and operates to press the link against a. flange 46 of hearing 40,with the resulting friction produced braking free pivotal movement. Thepivot axis of pivot means 40 parallels the pivot axis of pivot means 30.

With the window closed, the inner and outer fittings and link are allupright. As can be seen with reference to FIG. 2, first 90 movement ofthe window casement is accompanied with inward swinging of link 28 90,about the pivot axis of pivot means 30. With the link horizontal, as bedescribed, further movement of the link is prevented, (and when theeasement is swung further the casement and the inner fitting swing aboutthe axis of pivot means 40. When the window casement swings 90 from theposition of FIG. 2, the easement is completely turned about.

Projecting outwardly of inner fitting 24 is a finger 50. This finger, inthe position of the parts shown in FIG. 1, occupies a position to oneside of the pivot axis of pivot means 3 0. On swingingof the link andinner fitting between the positions of FIGS; 1 and 2, the'fing'er movesin an are extending about the pivot of pivot means side of the are thatthe finger moves in,.is an arcuate guide 52. The guide confines .thefinger on the parts pivoting between the positions of FIGS. 1 and 2,prevent the inner fitting from swinging with respect to the link untilthe link is horizontal. stitute disconnectable guide means assuring.proper sequence of movements in the parts.

There is also provided, at the base of arcuate guide 52, a stop 54projecting inwardly from outer fitting 20.

When finger '50 reaches the position shown in FIG. 1,

therefrom "is an abutment or stop 56.v In the position of the windowcasement shown in FIG. 3 the stop engages an edge of link 28topreventfunther rotation of the casement in' a clockwise direction. Inthe position of the casement shown in FIG. 2, the stop engages anotheredge of link 28 (extending normally of the. first-mentioned;

30 to the link in a counterclockwise direction. The stop edge) toprevent further rotation of thecasement relative limits pivotal movementof the easement and inner fitting The finger and guide .con'

relative to the link to movement over about a 90. angle. 7

It will be seen, therefore, that unfolding hinge h'as been providedwhich, when the window casement is closed,

is completely folded and devoid of any projections that I couldcatch'clothing, or produce an unsightly effect. "on initial 90 swingingof the window casement, the hinge provides for pivotal movement about anaxis extending through the window fraine, as is the case in the usualAfter reaching the horizontal position window swivel. 7 shown in FIG. 2,the window casement now pivots about the pivot axis provided by pivotmeans .40, which is now inwardly of the axis about which imti almovement occur-red, enabling the window easement on swinging properly.to clear the window frame. In all positions, free pivotal movement isbraked by the spring washers discussed.

I claim: 1. The combination of an outer window frame, a casement mountedtherein, swivel means on either side of the casement mounting it in saidframe andfaccommodating opening of the easement by swinging'it about ahorizontal axis through a 180 angle, said swivel. means comprising',with the casement'in a closed position, an upright outer'plate securedto the outside of the window casement, an upright inner plate secured tothe inside of the window frame at approximately the level of the outerplate, an upright interposed between the inner and outer plates andsubstantially aligned therewith,first pivot means connecting thelowerend of the link and the outer plate accomodating swinging of the upperend of the link in the direction of the inside of the window frame andthrough about a angle to a horizontal position, stop means between theouter plate and link limiting swinging of the link beyond thishorizontal position, second pivot means connecting the upper end of thelink and the upper end of the inner plate accommodating swinging of theinner plate about the pivot axis for the second pivot means with theplate swinging in the same direction that the link is swingable aboutthe pivot axis of the first pivot means, and stop means between theinner plate and the link limiting swinging of the inner plate relative.to the beyond a position where it is approximately at right angles tothe link, said outer plate having an arcuate guide I projecting towardthe inner plate that curves about the pivot axis of the first pivotmeans, and said inner plate having a finger projecting toward the outerplate confined by the guide so as to prevent swinging of the inner platerelative to the link during movement of the linkbetween its vertical andhorizontal positions.
